I share with you this small demo application which allows you to add and delete as many relations as you want, without going through a column each time. It is an easy alternative to the Trebuchet method.
I search to achieve this for a long time and finally found a method !!
This is made possible thanks to the new system of arrays, a little bit of “split text” and “template”. Very happy to have succeeded, this will allow me to add new features to my applications. I opened the app to everyone, you can test and copy it.
Hope this can be of help to you.
